Brunswick-Wolfenbuttel

The Principality of Brunswick-Wolfenbuttel (1269-1815) was a subdivision of Brunswick-Luneburg, with its history plagued by divisions and reunifications. Ruled by the Welfs, it was ruled by the Holy Roman Empire until 1806. Brunswick-Wolfenbuttel provided Hessians for service in the American Revolutionary War, and in 1815 the principality became the Duchy of Brunswick.
